Letters Patent No. 99,985, dated February 15, 1870.

' 'The Schedule referred lto in these Letters Patent and making part of' the same.

To all 'whom it may concern:

Be it known that we, FRIEDRICH WEGNER and ,CHARLES SoHLEETnIgof West Troy, count-yet Albany, State of New York, have invented certain new and useful Improvements in Chums; and we do hereby declare that the following is a specication thereof'.

The nature of our invention consists in the use of a drum or cylinder supported by a suitable framework and provided with suitable journals or shafts on which the said drum is to revolve.

The said drum is provided on the inside with bars or slats fixed stationary within, some ofthe said bars are placed longitudinally while others are placed laterally.

One end or head ofthe said drum is fixed while th'e other end or'head is detachable, and is secured in its place by means of' pins fixed in the said head, working info inclined grooves or slots made in the inner side of the said'drum, near its end.

A suitable door or entrance is provided on a side of the drum into which the milk or cream is passed. The said door is secured in place by means of a pivoted bar working into catches attached to the drum.

A suitable crank is also provided by which the drum may be revolved. l

One part of our invention relates to arranging inside of'a revolving drum two sets of' slats or bars, one

' set of' which runs longitudinally and the other laterally, both of which are iixed stationary within and revolve with the same.

'.lhese slats are made in frames, and workin grooves made in the inside of the drum, and can be removed when desired.

A part ofour invention relates to the manner of securing the detachable head in its place in the drum,

. and consists in the employment of pins fixed in the edge of the said head and workinginto inclined slots or grooves iliade in the drum inside near its end.

Figure 1 represents a perspective view of thc invention. Y

Figure 2 is a longitudinal vert-ical section of the Sit-Iller.

Figure 3 is a. lateral vertical section.

Figure 4 is a perspective view of' a section, enlarged, of' the drum and f'rame of slats of drum, with a portion ofthe bals or slats within the same; also the inclined groove for holding the head.

In the drawingsl A represents any suitable frame-work which supports the drum B, by means -of the shafts a a work ing into suitable bearings b b.

The drum B is constructed of wood, and is provided with one set of slats or bars, c, figs. 1, 2, 3, and 4, which run longitudinally inside, and another set ot' bars, e, which run from the centre to the sides.'

The said slats cand care made in frames, which frames are secured in their places in the inside ot' the drum by heilig slipped into the grooves d made in the inside of' the drum, as shown in figs. 3 and 4, while they are held at the center of the drum by -suit' able pins, f, attached to one set of frames and working in the other.

The drmn has one of its heads, B', fixed while the other head, C, is made detachable.

The said head C is provided 'with pins, g, fig. 2, which work into inclined grooves, h, shown in perspective view in fig. 4, made in the recess k of the said drum.

A short groove, h', leads from the face o' the recess to the said inclined groove 7i, by which the pins g are admitted to the said inclined groove h.

When the head C is placed in position at the end of the drum B wit-l1 the pins g entering the groove' h' and inclined grooves h, the said head is turned partially round, when the inclined groves h will cause the head C to draw tightly in its recess k and against the shoulder of the same.

Any suitable packing, such as rubber or its equivalent, may be used to make the connection between the drum and the head G Water-tight.

A spring-catch, lis also provided and secured to the head C, gs.'l and 2, which catches in the notch made in the drum and prevents the head (l from being accidentally turned round or loosened up.

Au entrance is made in a side of the drum, which entrance is closed by a suitable door or cover, D, suitably packed to prevent leaking.

The said cover or door D is secured in its place by A means of the bar m pivoted'to the said cover audworkiug under the catches n n, fig. 1.

To operate with this invention, the several frames or bars c and e are slipped in their places, the drum being previously removed from its frame A, or grooves d, when the head C is placed in the recess k, in such a manuel as will cause the pins g to fall into their respective grooves It and h, when the said head is partially turned round until the spring-catch Zfalls into itsA place, and the whole is locked.

The drum is then placed in its frame with its .shaft a a falling into its hearing.

Tile -cover D is then removed by pushing the pivoted borm to one side, so as tobe freed from its catches n a, when the milk or cream may be poured into the drum. f 1

Vhen' the desired quantity of cream to be operated upon has been poured in, tbe cover I) is put in place, and the bar mis operated in reverse and the cover secured.

The operator then revolves the drum by means of tbe crank jp, figs. l and 2, and in revolving,r the said drinn the lnlk or cream inside is partially carried up and dashed against the bars c and e, while at tbe same time the said bars c and e cui; through the cream, thereby greatly agibat-ing the same and breaking 'che globules and freeing tbe butter from the cream.

The revolutions of the drum are continued until all tbe butter hns been gathered from the milk or cream, when the drum can be removed i'om ibs frame and
